Controller
The CXT Controller is primarily designed to control systems
with short time constants and fast response times. This
would typically be the control of heat exchangers, non
storage calorifiers or ventilation plant where the sensor is
placed directly in the controlled medium. The CXT operates
24Vac actuators on two or three port valves. It is capable of
operating single or two stage systems.
FEATURES
• Easy to install and commission
• Shipped with typical default values for the
parameters, decreasing commissioning time
• Quick set mode allows basic settings to be easily
checked and set
• Simple override switch
• Operates single or two stage systems
• Night Set Back (NSB) and set-up inputs
• Supports new or old generation Satchwell sensors
• Remote setting input for room set value (RPW)
• Cost effective upgrade of all obsolete Climatronic
controllers
The CZT Controller is designed for use in systems such as
room or return water control. the CZT can be used for single
or two stage control. the CZT is suitable for use with 0 to
10Vdc actuators and/or step controllers.
FEATURES
• Easy to install and commission
• Shipped with typical default values for the
parameters, decreasing commissioning time
• Quick set mode allows basic settings to be easily
checked and set
• Simple override switch
• Operates single or two stage systems
• Standard 0...10Vdc output
• Night Set Back (NSB) and set-up inputs
• Existing CZT sensors can be used
• Remote setting input for room set value (RPW)
• Cost effective upgrade of all obsolete Climatronic
controllers
The FLS is a Step Control Function Module which is
designed to be used in conjunction with
0 to 10Vdc output Controllers thus providing a stepped
on/off output from one or more stages.
FEATURES
• Six steps available
• Indication LEDs show status of each relay step
• Provides step control of electric heaters and alike
• Panel mounting optional
The KMC Controller can be used to control humidity or
temperature in ventilation and air conditioning systems. The
KMC uses Satchwell sensors to monitor humidity or
temperature and control the plant.
The KMC is designed to carry out the general control
functions of the Satchwell KZT, KZH and KET controllers with
the added benefit of a digital display.
The KMC control stage outputs are all 0...10Vdc, except the
single stage humidity application that has an optional 24Vac
pulsed output.
The controller can be configured to run in one of the
applications by simply selecting that application number.
1. Single Stage Humidity Controller
2. Two Stage Humidity Controller
3. Single Stage Temperature Controller
4. Two Stage Temperature Controller
5. Three Stage Temperature Controller
FEATURES
• Direct digital control
• Programmed via the keyboard and display
• Digital display provides comprehensive indications of
all current parameter values, settings and
measurements
